This update is only compatible with the North American, South American, and Western European versions of Gears of War. If you are running the Russian or Eastern European versions of Gears of War then you will be unable to install the update. The Eastern European versions of the game include the Polish, Czechoslovakian, and Hungarian language versions of Gears of War for Windows. This has no impact on single- or multiplayer gameplay/connectivity.

Windows gamers can look forward to the “Gears of War” experience for the very first time, and will get to choose between doing battle via mouse and keyboard, or using the Windows-enabled Xbox 360 controller. From renowned developer Epic Games, “Gears of War” for Windows will engage gamers in hyper-realistic combat, allowing players to fight for survival against the Locust Horde, a nightmarish race of creatures that surface from the bowels of the planet.

In addition to retaining all of the content from its Xbox 360 counterpart and all previously released downloadable content (seven multiplayer maps and the Annex game mode), “Gears of War” for Windows will feature exciting original content, all-new Achievements to unlock, and ultra-high resolution visuals. Five new campaign chapters expand upon the riveting story (including an epic battle with the fearsome Brumak), and the action-packed multiplayer offering is bolstered with three exclusive multiplayer maps, a “King of the Hill” game type, and Games for Windows – LIVE support to deliver online matchmaking for Gold members. A new game editor will allow users to develop an unlimited number of user-created levels with complete access to the Unreal Editor.

Features :

Frag-filled new content. "Gears of War" will feature locations that are unique to the franchise and the genre. Players will encounter all their favorite foes from the Xbox 360 version; however, these intense encounters will take place in some new environments and allow players to manipulate the new game modes and technology found only in the Games for Windows title. Boasting three new multiplayer maps, a new multiplayer game type, Game Editor, five new campaign chapters and DirectX 10 support, "Gears of War," will challenge and push the limits of the PC gaming experience and provide an unparalleled visual presentation.

Engaging and disturbing cinematic story. Movie-like cut scenes, cinematic camera moves and in-game storytelling bring the brutal, emotionally charged narrative to life. Gamers control Marcus Fenix and his fire team as they pit advanced technology against the overwhelming and horrific Locust Horde.

Unmatched online gaming. "Gears of War" will tap into the power of Games for Windows — LIVE to deliver online matchmaking for its Gold account members. The service will enable gamers around the world to connect via their PCs, allowing players to experience individualized matchmaking, view player statistics, earn player Achievements, customize games and create personalized profiles.

New Game Editor. The game will also feature the all-new Game Editor, guaranteeing new user-generated content in the future. The "Gears of War" community will be able to tap its endless creative potential to develop an unlimited number of user-created levels through complete access to the Unreal Editor. Using the new engine, players can now import custom artwork into the engine, create particle systems, scripted encounters, cinematics and more.

Astounding visuals in next-generation gaming. "Gears of War" ushers in the next generation with incredible visuals, pushing DirectX 10 visual designs and bringing out the smallest details in the largest battle. Gamers experience a rich, dynamic world with a supreme level of detail. Characters come to life with unbelievable model quality and a physics-integrated animation system that has them truly reacting intelligently to events unfolding around them.

Hyper-realistic and intense combat. In "Gears of War" the battlefield is a lethal place — to foolishly stand out in the open is to invite an untimely demise. To survive, gamers must employ strategy, take cover using the interactive and dynamic environments, and suppress the enemy with blind fire, using their weapons and teammates to outwit and outfight their terrifying enemies.

Gears of Waris currently available on Xbox 360, and will launch on PC Nov. 6, 2007.
